Description
Overview
The Alestes Blue Sheen Tetra is a striking and relatively rare species of tetra known for its shimmering blue coloration and active schooling behavior. These fish are an excellent choice for aquarists looking to add a touch of vibrancy to their freshwater aquariums. Growing to a moderate size, they are best suited for spacious community tanks with compatible tank mates.
Origin
Native to freshwater rivers and streams of West and Central Africa, the Alestes Blue Sheen Tetra thrives in warm, slow-moving waters with abundant plant life and hiding spaces. Their natural habitat consists of soft, tannin-rich water with plenty of swimming space.
Feeding
These tetras are omnivores and require a varied diet to maintain their health and coloration. They readily accept high-quality flakes, pellets, and frozen or live foods such as bloodworms, daphnia, and brine shrimp. Supplementing their diet with vegetable matter or spirulina flakes helps promote optimal health.
Tank Mates
Alestes Blue Sheen Tetras are generally peaceful but should be kept in groups of at least 6 to 8 individuals to reduce stress and encourage natural schooling behavior. They mix well with other medium-sized, peaceful fish such as:
Other African tetras (e.g., Congo Tetras)
Gouramis
Corydoras catfish
Peaceful cichlids like Kribensis
Rainbowfish
Avoid housing them with overly aggressive or fin-nipping species that may cause stress or injury.
Aggression
While primarily peaceful, Alestes Blue Sheen Tetras can show mild aggression if kept in too small groups or if housed with significantly smaller tank mates. They may display occasional fin-nipping behavior if stressed or not provided with enough space.
Experience Level
Intermediate – These tetras require a stable environment, high water quality, and a sufficiently large tank, making them best suited for aquarists with some experience in fishkeeping.
Water Parameters
Temperature: 22-28°C (72-82°F)
pH Level: 6.0-7.5
Hardness: 4-15 dGH
Tank Size: Minimum 30 gallons for a small school, larger for a community setup
Filtration: Moderate to strong, with good water movement to mimic their natural habitat
Conclusion
The Alestes Blue Sheen Tetra is a stunning and active fish that can make a great addition to a well-maintained freshwater aquarium. With proper care, a balanced diet, and a suitable tank setup, these fish can thrive and display their full iridescent beauty.
